Planting joy of Purim within the soul

שמעתי מפי מו"ז ז"ל על הגמרא רבי נטע נטיעה בפורים ומסקינן נטיעה של שמחה נטע.

I heard from my grandfather, of blessed memory, on the Gemara that Rebbi planted a planting on Purim, and we conclude that it was a planting of simcha (joy) that he planted.

The Sefas Emes brings a teaching from his grandfather on a passage that speaks of "planting" on Purim — the Gemara resolves that this refers to planting joy.

שרמזו בזה כי בפורים יכולין ליטע נטיעת שמחה בלב האדם לשמוח בעבודת הבורא ית' כו'.

For they hinted with this that on Purim one is able to plant a planting of simcha in the heart of a person, to rejoice in the avodah (service) of the Creator, may He be blessed, etc.

The "planting" is metaphoric: Purim has the special power to implant a lasting joy in serving Hashem within a person's heart.

דהנה כתיב ליהודים היתה אורה ושמחה כו'.

For behold it is written, "For the Yidden there was light and joy, etc." (Esther 8:16)

He cites the verse describing the salvation of Purim, where the Jewish people experienced light and joy.

וחז"ל דרשו על התורה ויו"ט ומילה ותפילין כו'.

And Chazal expounded this on Torah, Yom Tov, milah (circumcision), and tefillin, etc.

Our Sages explained that "light" refers to Torah, "joy" to Yom Tov, and the other terms in the verse to milah and tefillin.

והענין הוא כי כל המצות הם הדרכות לאדם למצוא הארות המיוחדים לכל מצוה ומצוה.

And the idea is that all the mitzvos are guidance for a person to find the special illuminations unique to each and every mitzvah.

Each mitzvah is a path that draws out a particular spiritual light meant to be revealed through it.

ובאמת העיקר כשהאדם עצמו מוצא אלה ההארות בלבו.

And in truth the main thing is when the person himself finds these illuminations within his own heart.

The deepest level is not just to perform the mitzvah but to internally discover its light within oneself.

והוא בחי' תורה שבע"פ.

And this is the aspect of Torah she'baal peh (the Oral Torah).

This inner discovery within the person corresponds to the Oral Torah, which lives within Klal Yisrael.

דחיי עולם נטע בתוכינו היא בחי' תורה שבע"פ.

For "eternal life He planted within us" — this is the aspect of Torah she'baal peh.

The phrase from the berachah, "eternal life He planted within us," refers to the Oral Torah implanted inside us — connecting back to the theme of "planting."

וכמו שמצד תורה שבכתב יש זמנים שנותנים שמחה כמו ושמחת בחגך.

And just as from the side of Torah she'biksav (the Written Torah) there are appointed times that give joy, as in "and you shall rejoice on your festival,"

The Written Torah fixes external times of joy, like the command to rejoice on Yom Tov.

וכמו כן ע"י רשימת מילה ותפילין מתגלה הארת הקדושה בנפש האדם.

And likewise, through the imprint of milah and tefillin the illumination of kedushah (holiness) is revealed in the soul of the person.

Milah and tefillin leave a holy "imprint" that brings out the light of kedushah within a person's nefesh.

כמו כן נמצא בנפש האדם עצמו לעורר אלה הדברים.

So too there is found within the soul of the person himself the ability to awaken these things.

Beyond the external mitzvos, the person's own soul has the capacity to arouse these very illuminations from within.

וז"ש ליהודים היתה אורה כו'.

And this is what is said, "For the Yidden there was light, etc."

This is the depth of the Purim verse — the light shone in their very souls.

בעצם נפשותם.

In the very essence of their souls.

On Purim the light was not external but was revealed in the inner essence of the people themselves.

כענין שאמרו בשבת אין צריך תפילין שהם עצמם אות ובחרנו במ"א באורך.

Like the matter they said, that on Shabbos one does not need tefillin, for they themselves are a sign — and we have elaborated on this elsewhere at length.

On Shabbos the holiness is so internalized that the external "sign" of tefillin is unnecessary, because Bnei Yisrael themselves are the sign; the same applies to Purim's inner light.

ומגילה זאת נקראת אגרת ונקראת ספר כדאיתא בגמרא והיינו שהוא ענין ממוצע וחיבור מתורה שבכתב לתורה שבע"פ שהרי אז התחיל שורש תורה שבע"פ אנשי כנה"ג ובית שני:

And this Megillah is called an "iggeres" (letter) and is called a "sefer" (book), as is brought in the Gemara — and this is because it is an intermediate matter and a bridge from Torah she'biksav to Torah she'baal peh, for it was then that the root of Torah she'baal peh began, the Anshei Knesses HaGedolah and the Second Temple.

The Megillah is called both "letter" and "book" because it stands between the Written and Oral Torah, marking the very era when the Oral Torah began to take root through the Men of the Great Assembly during the Second Bais Hamikdash.

Summary: Purim has the power to "plant" an enduring joy in the avodah of Hashem deep within a person's heart, because its light is the light of the Oral Torah — a holiness revealed not externally but in the very essence of the soul, fittingly marking the era when Torah she'baal peh first took root.
